Great app, but it needs improvement

Don't get me wrong, I've tried a lot of apps for writing my math; this is the best one on the app store by far

However, when your equation starts getting long, as mine usually do, it'll start crashing whenever you start a new line. Thankfully, it will usually still save your previous line, but it gets pretty annoying at times.

Other than the suggestion to add compatibility for piecewise functions and to make it possible to erase fractions without deleting the content of the fractions, I don't anymore negative things to say about it.

I'm convinced the people who struggled to understand the app simply don't want to look for things. Simply put, there are a lot of symbols in math. In Nuten, these symbols are compartmentalized. When you first start using it, you may have to check each compartment for a symbol until you adjust to the layout, it's that simple.

Good app, but needs more

I love being able to write down formulas that I need to remember and being able to write down stuff with ease. But you can’t copy and paste, you can’t make simultaneous equations, you can’t put matrices, if you could add these this would deserve 5 stars, but for now, it’s 4

HORRIBLE !!!!!!!

You can’t just insert an exponent … say by holding down a number key. You can’t copy and paste. You can’t have it be a keyboard you can access as a keyboard. You can only view it vertically on an iPad. It doesn’t rotate to horizontal. I can’t believe someone developing a math keyboard wouldn’t or couldn’t think everything out. This is a very poorly designed app. F.
To get x2 (squared), I had to send, not copy, to my notepad, then copy and paste from the notepad. I can type x2 (superscript) within the app, but not from anywhere else, nor from the keyboard itself.
